The Obamas’ $11.75 million Martha’s Vineyard estate is expected to be the site of a controversial outdoor birthday bash this weekend.

Former President Obama and his FLOTUS purchased the sprawling 29-acre estate on the Edgartown Great Pond in December 2019 after previously renting it, The Post previously reported.

Now, Barack and Michelle are inviting 475 big-name guests to a 60th b-day blowout for the 44th US president, who was born on Aug. 4, 1961. The packed party will also be staffed by 200, The Post reported Monday morning.

Despite the fact that the outdoor Massachusetts party requires vaccinations, something the ex-president has advocated for, the get-together has been criticized for assembling a large number of people during the pandemic.

One thing’s for sure — the Obamas’ A-list pals will have plenty of space should they need to seek shelter: The interior of the 6,900-square-foot house has seven bedrooms and eight-and-a-half bathrooms. It has a vaulted ceiling living room with a stone fireplace, a chef’s kitchen and a formal dining room with a wall of windows, according to Realtor.com.

The kitchen has a breakfast room in the first story of a dodecagon — 12-sided — attachment on the house. Upstairs is positioned as a 12-sided conference room in listing photos.

The primary bedroom suite has a fireplace and a private sundeck, according to the listing.

Outside, the home has a screened porch, a garden, a stone patio, a pool with a hot tub and an outdoor shower, according to the listing.

The two-story home was built in 2001 by Celtics owner Wycliffe Grousbeck and his ex-wife Corinne Grousbeck, according to property records.

President Obama and his family have also rented other houses in Martha’s Vineyard.

Obama’s former second-in-command, President Joe Biden, will reportedly be unable to attend his big 6-0 soiree. However, Oprah Winfrey, George Clooney and Steven Spielberg are reportedly among the invited guests, The Post reported.

For his 50th, President Obama hosted Jay-Z, Stevie Wonder, Tom Hanks and Chris Rock at a party at the White House.

Barack, who is now a minority owner of NBA Africa, has two daughters, Malia and Sasha, with his wife Michelle. Michelle Obama stars in the Netflix series “Waffles + Mochi” and has a best-selling memoir, “Becoming.”

Representatives for the Obamas did not return The Post’s request for comment.
